End User Influence on Fibre Channel

• Fibre Channel is in a unique position due to its large install base and longevity

• This distinguishes Fibre Channel from other storage transport technologies

• Many requirements being addressed by the INCITS T11 FC Standards Committee are based on REAL end user experience and input

• This has lead to the development of many new Fibre Channel features and enhancements

ISLs are used for non-edge, core connections, and other high speed applications demanding maximum bandwidth. Except for 100GFC (which follow Ethernet), †Equivalent Line Rate: Rates listed are equivalent data rates for serial stream methodologies.‡ Some solutions are Pre-Standard Solutions: There are several methods used in the industry to aggregate and/or “trunk” 2 or more ports and/or data stream lines to achieve the core bandwidth necessary for the application. Some solutions follow Ethernet standards and compatibility guidelines. Refer to the FCoE page 4 for 40GFCoE and 100GFC0E.

Fibre Channel over Ethernet tunnels FC through Ethernet.  For compatibility all 10GFCoE FCFs and CNAs are expected to use SFP+ devices, allowing the use of all standard and non standard optical technologies and additionally allowing the use of direct connect cables using the SFP+ electrical interface.  FCoE ports otherwise follow Ethernet standards and compatibility guidelines.

‡Dates: Future dates estimated

* It is expected that 40GFCoE and 100GFCoE based on 2010 standards will be used exclusively for Inter-Switch Link cores, thereby maintaining 10GFCoE as the predominant FCoE edge connection

Innovations – FCoE

• Data Center Bridging (DCB)– Previously known as Data Center Ethernet (DCE),

Converged Enhanced Ethernet (CEE)– Enables 10GbE I/O consolidation– Consists of Priority Flow Control, Congestion Notification,

and Enhanced Transmission Selection at IEEE 802.1 levels

• FC over Ethernet (FCoE) – Ethernet encapsulates FC; another upper-layer protocol– Managed like FC at initiators, switches, storage systems– Same cabling (SFP+) for 8GFC and 10G FCoE

6th FCoE Plugfest (May ‘11)

• Testing the interaction of FCoE end devices with DCBx switches. This will validate that FCoE devices operate properly with PFC (Pause) and other Ethernet traffic in a Data Center Ethernet environment

• Using only the standard BB5 frame format and standardized that all devices must use FIP

• Enhanced Transmission Selection is now in the test plan. Manages the bandwidth of the links

16GFC Overview

• What is driving 16GFC– Prolific applications, server virtualization, multi-core processors,

more memory, solid state drives, PCIe 2.0, traffic aggregation, VDI

• Benefits of 16GFC– Higher performance leads to fewer links, easier cable

management, less power consumption per bit

• Defined by the following standards– FC-PI-5, Complete in T11, in public review at INCITS

– FC-MSQS, Complete in T11, in public review at INCITS

– FC-FS-3, Complete in T11, in public review at INCITS

Page 20: Fibre Channel  Driving Storage Innovation, Speed and Convergence

16GFC Backward Compatibility

• To improve the efficiency of the protocols, 16GFC only uses 64b/66b coding that is 98% efficient– 8b/10b codes used for 2/4/8GFC are 80% efficient

– 16GFC signals can not use the 8b/10b encoders

• To be backward compatible with 2/4/8GFC, 16GFC ASICs need to support both 8b/10b and 64b/66b coder/decoders (codec) on each link

• During speed negotiation, the transmitter and receiver switch back and forth between the speeds (and the corresponding codecs) until the fastest speed is reached for a given link

Page 21: Fibre Channel  Driving Storage Innovation, Speed and Convergence

16GFC Speed Negotiation

• During speed negotiation, the speed dependent switch routes the initialization sequence to the appropriate encoder– 64b/66b for 16GFC

– 8b/10b for 2/4/8GFC

– The coupler sends the signals from one the encoders to the SFP+

Innovation – 32GFC

• Highlights of FCIA 32GFC MRD for T11 standard – Stay serial and single-lane; 28.05Gbaud– T11.2 FC-PI-6: Stable by August ‘11, release Feb ’12– 70 to 100 meters on OM3 optics, 7 meters on copper– <=50% Watts/Port of 40GE and <=50% $/port of 40GE

• 2014 products– Leverage work from multitude of technologies

• “Perfect Storm” flocking towards 25Gbaud range

• Expect feasibility for FC core markets around 2014-2015– Ethernet 100G mandates a 25G/lane technology 2015– IB will have 25G per lane option in 2014/2015

• 8GFC you buy today will work with 32GFC

FC-SCM Behaviors

• Management Tools– The set of behaviors provided by a host, switch, or storage device that a

management tool running locally in that host, switch, or storage device may use to manage an SCM environment

• Hosts– The set of behaviors required to allow a Host, including a Host Bus

Adapter, to be used to manage a SCM environment and be managed in an SCM environment

• Fabrics– The set of behaviors required to allow a Fabric to be used to manage an

SCM environment and be managed in an SCM environment

• Storage– The set of behaviors required to allow a Storage device to be used to

manage an SCM environment and be managed in an SCM environment

Page 27: Fibre Channel  Driving Storage Innovation, Speed and Convergence

Some FC-SCM Examples

• An SCM Switch shall support 256 entries in the name server database

• An SCM Switch shall support 256 entries in the Fabric Configuration Server database

• An HBA shall provide the following Name Server attributes for each of its ports:– Symbolic Port and Node Names,

– Port Types,

– FC-4 Types and Features

• A switch shall default its configuration to operate in Enhanced Zoning mode.

Fabric Device Management Interface (FDMI)

• Part of the Management Server• Allows HBA Information to be Obtained from the

Fabric• Based on the HBA API standards• Allows static and dynamic information associated

with HBA’s to be obtained from a single point

Page 30: Fibre Channel  Driving Storage Innovation, Speed and Convergence

Enhanced Commit Service

• Two phase commit protocol used to update Fabric databases– Examples include the Zone and Policy Databases

• Provides Additional Function– Application Level Locking

– Advanced Error Recovery

– Transaction Semantics

Page 31: Fibre Channel  Driving Storage Innovation, Speed and Convergence

Inter-Fabric Routing

• Allows Devices on Separate Fabric to Communicate Without a Merge

• Two Modes of Operation– Simple Mode

– NAT Mode

• Uses an Inter-Fabric Router for both modes of operation

• Includes Inter-Fabric Zoning

Page 32: Fibre Channel  Driving Storage Innovation, Speed and Convergence

Inter-Fabric Zoning• Sets up devices on separate Fabrics to communicate• The zoning databases on each Fabric must have the

device pairs configured• Even though it is Inter-Fabric, the normal Fibre

Channel database and access service is used• Routers exchange zoning data bases across the

Fabric• This is achieved using the Inter-Fabric Zoning

protocol (see FC-IFR)

Page 33: Fibre Channel  Driving Storage Innovation, Speed and Convergence

N_Port ID Virtualization

• Allows Multiple Virtual N_Ports to exist behind a physical N_Port

• Normal FLOGI Occurs for the first Login• Subsequent Logins Request FC-IDs using the FDISC

ELS• Enables Virtual Machine Environments

– Each Virtual Machine is able to have its own WWN and FC_ID

• Enables N_Port Virtualizers

Page 34: Fibre Channel  Driving Storage Innovation, Speed and Convergence

Virtual Fabrics (Frame Tagging)

• Applies the Virtual Machine Paradigm to the Switch• Provides for Multiple Virtual Switches in a Single

Physical Switch• Each Virtual Fabric (SAN) Runs an Instance of the

FC Services• Provides for Isolation by Carving Up the Physical

Fabric into Multiple Virtual Fabrics• Routing Tables are Indexed by the 12 bit Fabric ID

Field in the Frame

Virtual Channels

• Multiple Virtual Channels on ISLs• Allows Traffic Differentiation• Three Assignment Schemes

– Simple, Two Virtual Channels, Class F and All Others

– Fixed, Based on D_ID with class F and Broadcast assigned

– Variable, Based on D_ID with class F and Broadcast not assigned

• Each VC Has Own Set of BB Credits– Negotiated During ELP

Page 37: Fibre Channel  Driving Storage Innovation, Speed and Convergence

Updated FC Port Model

• Drivers such as virtualization have driven the definition of a new FC port model– The new model is defined in FC-SW-5 and FC-FS-3

• The new model modifies the FC-2 level• FC-2 defines the basic link level functionality• FC-2 is now divided into 3 new sub-levels

Page 38: Fibre Channel  Driving Storage Innovation, Speed and Convergence

• Dominates the SAN market• Well understood• Easy to learn, use and implement• Protects and future-proofs storage investments• Provides comprehensive solutions• Vision for extending into additional markets• Continuous speed & Bandwidth/$ improvements• Listening to customer needs• Aggressively pursuing Energy Efficiency
